The Full Cast of Deadpool 2

Reynolds is reprising his role as the Merc With a Mouth.

Brolin, who already plays Thanos in the Marvel Universe, will be tackling the role of Deadpool's buddy Cable.

In an January interview with Collider, writers Rhett Reese and Paul Wernick confirmed that Hildebrand's character, Negasonic Teenage Warhead, will "at least make an appearance."

In the same interview, they revealed Colossus will also be back. The character is CGI, but he is voiced by Kapicic.

In March, Ryan Reynolds tweeted a cryptic casting announcement, revealing that Atlanta star Beetz is playing Domino. She's a superhero with the ability to manipulate luck. She also happens to be Cable's lover.
